ABSOLUTE MAXIMUM RAT INGS
These are stress ratings only and functional operation of
the device at these ratings or any other above those
indicated in the operation sections of the specifications
below is not implied. Exposure to absolute maximum
rating conditions for extended periods of time may affect
reliability.

Note 1: Maximum power dissipation can be calculated
using the formula: PD = (T J(max) - TA JA, wLJhere

maximum allowable power dissipation will result in
excessive die temperature and the regula
